Avaya 03-300430 User Manual

Notes:

a. Error Type 0: run the short test sequence first. If every test passes, run the long test 

sequence. Refer to each appropriate test’s description, and follow its recommended 
procedures.

b. Error Type 18: The D channel is demand busied out. No calls can be made over this 

D channel.

c. Error Type 130: the circuit pack or media module has been removed or has been insane for 

more than 11 minutes. To clear the error, reinsert or replace the circuit pack or media 
module.

d. Error Type 1537: Link error. This error occurs when the port receives an invalid frame over 

the D channel. This error normally indicates an off-board problem usually related to 
transmission errors on the DS1 facility. Execute list measurements ds1-log for the 

UDS1 TN464 circuit pack or MM710 Media Module where the D channel resides. If the 
UDS1 or MG-DS1 is reporting some errors, then the DS1 facility has experienced 
transmission problems that could have caused the ISDN-LNK to report a Link Error.

If the UDS1 or MG-DS1 is not reporting errors, execute the long test sequence for the D 
channel. Investigate any errors. If there are none, execute a long test sequence for the 
UDS1 circuit pack (UDS1-BD) or MM710 Media Module (MG-DS1). Investigate any errors.

If no errors could be found by testing, the Link Error is probably not affecting service. 
However, if this Link Error continues to be logged, follow normal escalation procedures.

e. Error Type 1793: UDS1 Interface circuit pack or MM710 DS1 Interface Media Module is out 

of service. Look for and resolve UDS1-BD or MG-DS1 errors in the Hardware Error Log.

f. Error Type 3585: transmit FIFO Overflow error. The circuit pack is having problems 

transmitting data to the packet bus, thus affecting the conveyance of signaling information 
over the D channel. Specifically, this error occurs when the packet-bus transmit buffers 
overflow. This condition probably indicates a hardware problem.

The actual alarming level will depend on the options chosen via set options on the 

G3-MT terminal. ISDN-PRI Signaling Link port alarms are treated as Station alarms, and 
their default alarming option is to downgrade every alarm to Warning. The value shown in 
the preceding table indicates the normal, unfiltered case (option “y” on the set options 
screen).

: This error type does not occur on the G700.

g. Error Type 3841: Bad DLCI error. This error occurs when a LAPD frame is received across 

the DS1 facility that contains a DLCI that does not have a valid entry in the on-board 
translation memory. This error normally indicates an off-board problem usually related to a 
broken endpoint or a state mismatch between a remote endpoint and the local 
call-processing software. Maintenance will not start any testing or generate any alarms in 
response to this error.
